1. A utility system comprising:
- a first mesh gate associated with a first network in communication with a first utility meter associated with a distribution circuit, the first utility meter adapted to read first meter information over a period of time and monitor switching events, and the first mesh gate adapted to transmit the first meter information over a second network;
a second utility meter synchronized with the first utility meter and associated with the first mesh gate of the first network, the second utility meter associated with the distribution circuit and adapted to read second meter information over the period of time and monitor switching events, the first mesh gate further adapted to transmit the second meter information over the second network;
a utility control system located remote from both of the first utility meter and the second utility meter, wherein the utility control system issues an initiation of a switching event to impact the distribution circuit, wherein the switching event comprises activation of a tap changer or capacitor bank on the distribution circuit, and wherein the first and second utility meters are responsive to issuance of the switching event to begin synchronized monitoring of the distribution circuit; and
a server adapted to receive the first and second meter information from the first mesh gate via the second network, so that the server determines if the switching event had a desired effect, based on synchronized first and second meter information,wherein in response to issuance of the switching event, the server is triggered to monitor the first meter information and the second meter information so as to determine the impact of the switching event on the distribution circuit.

Abstract
Embodiments of the invention propose volt/VAR optimization that may be time synchronized and automated based on actions invoked at a control system utilizing a smart grid solution that incorporates metering end points which are capable of reporting to a utility the information that is needed by the utility or to another system for making real time decisions on events that may occur at the distribution level. Embodiments of the invention incorporate large numbers of end points (e.g., smart meters) which a utility can use to determine how any event or events it may invoke at the grid level affect its compliance at the end user level.

14. A method comprising:
-
in response to a switching event issued so as to cause a desired effect on a distribution circuit, receiving, by a head end server associated with a mesh network, a first meter information from a first utility meter associated with the mesh network and associated with the distribution circuit; in response to the issued switching event, receiving, by the head end server, a second meter information from a second utility meter synchronized with the first utility meter, the second utility meter associated with the mesh network and the distribution circuit, wherein the switching event comprises activation of a tap changer or capacitor bank on the distribution circuit, and wherein the first and second utility meters are responsive to issuance of the switching event to transmit synchronously monitored first and second meter information; transmitting, by the head end server, the first and second meter information to a utility server; determining, by the utility server, based on the first and second meter information received in response to the issuance of the switching event, if the switching event had the desired effect. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
